      45% is four 10 percents + one 5 percent = 4*8 + 1*4 = 36.. simpler than the traditional method..

    Just multiply by moving two decimals is way easier and faster.

    or (15 x 80) / 100 to make it even easier.

  • @bennemann

    I have a cool technique for percentages of large numbers. I divide numbers into their tens, hundreds, thousands etc. constituents, apply the percentage to each one, them sum the results. So to do 20% of 1485 (composed of 1000, 400, 80 and 5), I do:
    (20% of 1000) + (20% of 400) + (20% of 80) + (20% of 5)
    = 200 + 80 + 16 + 1
    = 297

      +bennemann 20% is the same as 1/5 so just divide 1485 by 5 ( =297) ... or divide by 10 and double your answer. e.g. 1485 /5 = 297 or 1485/10 = 148.5 the x 2 = 297

    Basicly in easier ways lets say 55% of 360
    so what you would do is divide 360÷100=3.6
    so you take 3.6 and multiply it by 55% and you get 198 as seen in video hope this helped :)

He would make a wonderful story teller. I do wonder if people from other countries realise that we Australians find their accent hard to understand at times.Interesting these people have all been helped for free in these videos.

    I just find 1% of the quantity and then multiply by the percentage they ask for. For example if they ask for 8% of 25 I find 1% which is .25 then times by 8 which becomes 2.

    I'm not joking when I say this just changed my life. I moved from England ( the land of not tipping servers, mainly) to Canada ( tip everyone ) and I've always struggled to figure out the 15 percent tip. I usually didn't bother and guessed because my teachers said I was stupid, and that stuck with me. The simplicity of it blows my mind! I'm staying up all night to study math now...and a big middle finger to all you math teachers who could not explain math in a way that I could understand. Thanks tecmath. :)

    When the percentage is a two digit number its always gonna start with a decimal
    45% of 80
    .45×80=36
    ---------------------
    When the percentage is only one digit start with your decimal but add a zero followed by your percentage
    4% of 80
    .04×80=3.2
    This method gets rid of the subtracting Hopefully this helps and is understandable.
